BED SILL FOIL PILEDRIVERS.

Specification of Letters Patent.

Application filed March 25, 1921. Serial No. 455,561.

To all whom 2'25 mag concern:

'Be it known that I, HERMAN R. SMITH, a citizen of the United States of America, residing at Brooklyn, in the county of Kings and State of New York, have invented cer tain new and useful Improvements in Bed Sills'for Pile Drivers, of whichthe following is a full, clear, and exact description.

Thisinvention relates tobedsills "for pile drivers, and its chief object is toprovide a bedsill composed of sections, which can be secured together in a simple and effective manner for use and which can be readily taken apart'tor convenience.inhandling and shipping. A further object is to provide a sectional bedsill -(on which the turntable revolves which supports the tower or lead) in which the several sections of the frame are locked together by removable keys driven In the preferred form or the invention. my improved bedslll lscomposedof a center section, and apair of wing-sections adapted to be arranged in the plane of the center section at the sides thereof, edge to edge. Each section in this form comprises a rectangular frame of steel members, as I-beams and channels, and the members at the meeting edges are provided withlaterally extending plates which overlap the adjacent section above and below, forming socket joints which are rigidly connected or locked together by vertical keys set .in vertically. aligned aper .tures in the cooperating parts of the joint. Each section of the frameis mounted on timberskids so that the assembled be'dsill can be shifted forwardly and rearwardly on the usual rollers, and atthe center of the middle orcent'erlsection is a bearingior the turntable pivot. Each section also carries anarc of the rail-circle, composed preferabl of short lengths of T-rail bent to circullir form. v The embodiment outlined above is illustrated in the accompanying drawings, in which Fig. 1 is a plan view of the bedsill properl assembled.

.Fig. Qis alongitudinal section on the two planes indicated by the line 2-.-2 in Fig. 1. .Fig. 3 is a partial' cross section on'line 8 -3 of Fig. 1.

Fig. 1 is a detail'sectionon line l l, and 5 isa detail sectionon line 5-5 of Fig. 1, illustrating one of the socket-joints locked together by tapered keys.

F'g. 6 isa detail perspective view-yon a larger scale, showing one of the joints in theconrse of being assembled.

In the .bedsill illustrated the center section or the frame comprises two parallel laterallyspaced channels 10, 11, arranged withtheir flanges extending inwardly, and four transverse I-beams 12, 18, 1e15, at right angles to thelongitudinal side members 10, 11, rigidly and permanentlycohnected thereto by upper and lowergusset plates 16, 17. The transverse members .12-13and Mic-15 are connected by central longitudinal I-beanis 18, 19, of less height, attached thereto'by' gusset plates 20, 21, 22, 23. g V

y The two side or wing sections of the frame are composed oflongitudinal inner members 2%, 25,. in the form or channel irons with their flanges turned outwardly .(with respect to the adjacent members10, 11, otthe center sectionland longitudinal outer members in the formv of I-beams 26, 27, connected by: means of upper gusset plates 28, 29, and lower gusset plates 30, 31, to transverse I- beams 32, 38, 341, '35,- which are in alignment with the transverse members 12, 13, ll, 15 of the center section, as clearly shown in Fig. .1. The gusset .platesQIS, 30 are long enough to overhang the platesv16, I? on the center section, forming sockets to receive the latter, and "the four plates, which maybe conveniently termed hey-plates, are provided with apertures 36,'37,-in such ,position as to be invertical alignment wheirthe sections are assembled, toreceive the keys 38, as clearly indicated in Figs. 4, 5 and 6. As shown, the keys aretapered,-and the apertures are of corresponding size, so: that as the former aredriven intoplacethe sectionsof the frame are drawn firmly together. :Bending movements tendingto bend thecenter section or the wing section downwardly relatively to the other are taken in tension by the Patented Feb. 21, 1922.

39, having a central longitudinal rib 40, adapted to enter a corresponding groove 41 in an otherwise similar shear plate 42 on the adjacent channel member 24, 25, for the purpose of taking any shearing stresses which may be exerted on the sections at the joints. To provide wider bearing surfaces for the keys and to relieve the edges ofthe key apertures from excessive wear, the flanges of the channels 10, 11 are equipped with wear-blocks 43, Fig. 5, riveted to the flanges.

At the center of the main or center section of the bedsill frame provision is made for the bearing on which the pile driver turntable (not shown) rotates. For this purpose a flat plate 44 is riveted on top of the transverse members 13, 14, which, it will be seen, are closer to-each other than to the end members 12, 15. The plate is also supported by longitudinal channels 45, Fig. 3, connected to the members 13, 14 by angle pieces of which one is shown at 46, and is also supported centrally by two -flanged members or channels, of which one is shown at 47 in the figure just mentioned. The plate 44 is provided at its center with an opening 48 for the turntable pivot, not shown.

' The rail-circle, concentric with the bearing aperture 48, is composed of two T-rail sec-' tions 49, 50, arranged diametrically opposite for the rail sections on the wing frame-sec- I tions, these diagonal supports being in the form of channels or I-beams secured to the members 2527 and 2426 by means of angle pieces, as 57, Fig. 6. If desired, the several sections of the rail circle may be connected together by means of fishplates (not shown) secured by bolts through the holes 58, Fig. 6.

The swing-line, not shown, by which the turntable is revolved, encircles the rail circle on the outside, and to prevent the line from catching on the keys which lock the socketjoints outside of the rail circle, the upper socket-plates 28 (see Fig. 6) are provided with beveled elevations, as 59, over which the line can slide easily, and the keys are shortened so that their upper ends will be flush with or but slightly above the plates, as indicated in Fig. 3. 1

The center and side sections'of the frame are mounted on timber skids, 60, 61, 6 2,which extend longitudinally as indicated in Fig. 1.

It is here to be understood that the invention is not limited to the specific construction herein illustrated and described but can be embodied in other forms without departure from its spirit.

I claim:

1. A bedsill for pile drivers, comprising a plurality of bedsill sections arranged edge to edge in the same plane, cooperating looking devices at the adjoining edges to secure the sections releasably together, and a rail circle composed of arc-shaped rail sections abutting end to end and secured on the respective bedsill sections.
